V FLASH-LIGHT BA'FTERY 'THRUSI CAP.

Application filed August 114, 1922; Serial No. 581,597.

To all whom it may 0mm:

Be it known that I, EnMUNnR. BARAivr,

ajcitizen of the United States, residing in. the borough of Brooklyn, county of Kings,

city and State of ,New York, have invented certain new and useful Improvements in Flash- Light-Battery Thrust Caps, of which the followingis; a specification; f i

e This invention relates to flashlight battery thrust caps, such as are adapted ,to, be, Car-- ried upon the end oi a flashlight casing, and

has for one of its primary objectstheprd' vision of a simple andtefiicient meansfor exerting; a longitudinal thrust upon the flashlight battery, in order that the same may be maintained in a proper position within the flashlight casing under all conditions.

Other objects and certain advantages of my invention will become apparent from the following description, when taken in connection with the accompanying drawings, in which- Figure 1 is a side elevation of a flashlight having a cap embodying my invention asso ciated therewith.

Figure 2 is a horizontal sectional view taken on line 22 of Figure 1.

Figure 3 is a perspective view of a resilient thrust element.

In the drawing, wherein for the purpose of illustration, is shown what I at present consider the preferred form of my invention,

the numeral 5 indicates a flashlight casing,

provided with the usual form ofhead 6, having a conventional type of lens 7 associated therewith The opposite end of the casing, through which the battery indicated by the numeral 8 is adapted to be inserted, is screwthreaded, as shown at 9, and is adapted to receive thereupon the screw-threaded cap or closure 10, into which is fitted a resilient thrust element, indicated as a whole by the numeral 11. This thrust element is constructed from a suitable resilient material, and is so formed as to present substantially throughout its length an arcuate shape, most clearly shown in Figure 1.

In constructing the element 11, the ends thereof are slightly bent or curved in an op posite direction to the curvature of the main portion of the element to provide hooks 12, adapted to assume a position within the usual form of bead or groove 13, provided in the cap 10. By so constructing the ele-v ment .asto provide the; hooks 12, it is apparent that the same may be effectively revtained 111 a, proper posit-ion within the capi.

10 since the inherent resiliency ofithe elementtends to urge the books 12 into an intimate engagement'with the inner Wall of thebead 13. Inasmuch as the material from I 1 which the element ,11 ,isconstructedqis more be veffectively locked in position within, the 165 cap 10 when the endsflQ are forced into the or less resilient, in order that the same may groove 13,1 am enablednbystriking out a portion oftheelement,to provide a-resilient tongue 14.: By reasonof the fact that the tongue 14 is more or less resilient, it is apparent that when the cap 10 is run down upon the casing 5 a suflicient distance to place the tongue under more or less tension, the battery 8 will be urged under its influence along the longitudinal axis of the casing and maintained in a proper position therein.

Having thus described my invention, I I

claim:

l. A flashlight thrust cap comprising a closure, a resilient thrust element bent intermediate its ends and having a resilient tongue adapted to engage the flashlight battery, said ends being urged into intimate engagement with the wall of said closure by inherent resiliency of said thrust element whereby the same is maintained operatively positioned with respect to said closure.

2. A flashlight thrust cap comprising a closure, a bowed thrust element having a resilient tongue struck therefrom, said tongue being bent and adapted to engage the battery of the flashlight and exert a longitudinal thrust thereupon.

3. A flashlight thrust cap comprising a screw-threaded closure having a bead formed therein a resilient thrust element bent intermediate its ends and having its ends adapted to enter said bead, and a resilient tongue associated with said element, said tongue being adapted to engage the flashlight battery and exert a longitudinal thrust thereupon, whereas the ends of said thrust element are maintained within said bead by reason of the inherent resiliency of said thrust element.

a. A flashlight thrust cap comprising a closure having a bead, a resilient thrust element bent intermediate its ends and having its ends curved and adapted to enter said 0. of a-resilient-nature and bent intermediate bead, the ends of said element bein maintainedwithin said bead by reason 0 the in-' herent resiliency of said thrust element, and a resilient tongue struck up from said element,.said tonguebeing adapted to engage the flashlight battery and exert a longitudinal thrust thereupon.

5. A flashlight thrust cap comprising a closure having a bead formed therein, a bowed thrust element having its ends bent and adapted to enter said bead, and a bowed resilienttongue struck up from said element,-

said tongue being-"adapted to engage the flashlight battery and exert alongitudinal thrust thereupon; 3 i

6. A- flashlight thrust cap comprising a closure a thrust element arranged Within said-closure and having its'ends engaging the inner-*wall thereof, saidelement being "its ends whereby the same a'reurged in opposite directions into intimate engagement withathe wall of said closure.

37; A flashlight thrust cap comprising a ,closure, a thrust element arranged within said closure and having its ends engaging the inner wall thereof, said element being of a resilient nature and bent intermediate its ends whereby the same are urged in opposite directions into intimate engagement the inner wall thereof, said element being of a resilient'nature and bent intermediate its ends whereby the same are urged in opposite directions into intimate enga ement with the wall of said closure an resilient tongue carried by said thrust element, said tongue being bent intermediate its ends and adapted to engage the flashlight battery and exert a longitudinal thrust thereupon.

In testimony whereof, I have affixed my signature :to this specification.
